I have read through numerous posts on here as well as other forums about noises coming from the transmission area. However I canít seem to find anything that matches what I experience. It only happens around 2k RPM under acceleration, and any gear, and only for about the first 10 to 15 minutes of driving. Itís like a deep rattle coming from the trans. Itís not (at least I doubt it is) a heat shield because I know what that sounds like. The jeep has less than 1000 miles on it and it has done it since day one. I have attached a video link so you can hear it. Sorry for the chitty video, I was using my cell phone. Thanks for the help.
